Question

我尝试了以下代码，但列仍然继承了表的字段名称

   DataGridView1.DataSource = ds.Tables("student_attendance_table")
    With DataGridView1
        .RowHeadersVisible = False
        .Columns(0).Name = "Register No."
        .Columns(1).Name = "Date"
        .Columns(2).Name = "Year"
        .Columns(3).Name = "Batch"
        .Columns(4).Name = "Hour 1"
        .Columns(5).Name = "Hour 2"
        .Columns(6).Name = "Hour 3"
        .Columns(7).Name = "Hour 4"
        .Columns(8).Name = "Hour 2"
        .Columns(9).Name = "Attendance"
    End With

内容如下：

1138M0345   27-07-2013  3   1   P   P   P   P   P   P
1138M0346   27-07-2013  3   1   P   P   P   P   P   P
1138M0347   27-07-2013  3   1   P   P   P   P   P   P
1138M0348   27-07-2013  3   1   P   P   P   P   P   P
1138M0349   27-07-2013  3   1   P   P   P   P   P   P
1138M0350   27-07-2013  3   1   P   P   P   P   P   P
1138M0343   27-07-2013  3   1   A   A   A   A   A   A
1138M0344   27-07-2013  3   1   A   A   A   A   A   A

此外，我需要使用REGNO（第一列）按升序对内容进行排序

我正在使用vb.net

Answer 1

要更改列标题，请使用.HeaderCell.Value = "Display Value"

DataGridView1.DataSource = ds.Tables("student_attendance_table")
    With DataGridView1
        .RowHeadersVisible = False
        .Columns(0).HeaderCell.Value = "Register No."
        .Columns(1).HeaderCell.Value = "Date"
        .Columns(2).HeaderCell.Value = "Year"
        .Columns(3).HeaderCell.Value = "Batch"
        .Columns(4).HeaderCell.Value = "Hour 1"
        .Columns(5).HeaderCell.Value = "Hour 2"
        .Columns(6).HeaderCell.Value = "Hour 3"
        .Columns(7).HeaderCell.Value = "Hour 4"
        .Columns(8).HeaderCell.Value = "Hour 2"
        .Columns(9).HeaderCell.Value = "Attendance"
    End With

对于初始排序，您可以使用

DataGridView1.Sort(DataGridView1.Columns(0), System.ComponentModel.ListSortDirection.Ascending)

Answer 2

或SELECT rollno as 'RollNo', name as 'Name', class as 'Class' FROM student_tbl 这将重命名标题

Answer 3

或者"Data Grid Object".Columns("column index").HeaderText = "value"也适用。

Answer 4

DataGridView1.DataSource = ds.Tables("student_attendance_table")
    With DataGridView1
        .RowHeadersVisible = False
        .Columns(0).HeaderText = "Register No."
        .Columns(1).HeaderText  = "Date"
        .Columns(2).HeaderText  = "Year"
        .Columns(3).HeaderText  = "Batch"
        .Columns(4).HeaderText  = "Hour 1"
        .Columns(5).HeaderText  = "Hour 2"
        .Columns(6).HeaderText  = "Hour 3"
        .Columns(7).HeaderText  = "Hour 4"
        .Columns(8).HeaderText  = "Hour 2"
        .Columns(9).HeaderText  = "Attendance"
    End With

试试这个，我用的是同样的。为我工作！
